I don't buy pet health insurance, but I know that I can easily spend over $400 on medical bills for one of my dogs in a year. And I definitely spend more than $118 per dog on food. Let's not even get started about agility classes and trials!
Personal money management website, Mint.com, also looked at pet spending through their users. They found that the average person in the United States spends $112 per month on their pets (note that this number is for all pets in a given household). They also looked at variation by city. San Francisco spent the most money, $148 per month over the national average.
Obviously, there are many things that influence these numbers, but it's a good start to get people thinking about pet related expenses before they add a dog to the family.
How much do you estimate that you spend on each of your dogs in one year?
